MACHINERY FOR FINISHING CLOTH.

srncrrrcn'rron forming part of Letters Patent No. 685,951, dated November 5, 1901.

Application filed March 16, 1901.

To all whom it may concern:

Be it known that we, HENRY SUTCLIFFE SMITH and ANDREW THOMSON, subjects of the King of England, residing at Bowling Dye Works, Bradford, England, have invented certain new and useful Improvements in Machinery for Finishing Cloth, of which the following is a specification.

This invention relates to improvements in that class of machinery for finishing dress goods, suitings, linings, and other like fabrics in which the material treated is first eX- posed to heat and pressure to finish it and then to cold and pressure to fix the finish.

To fully describe our invention, reference is made to the accompanying sheet of drawings, forming a part of this specification, in which similar figures of reference indicate Figure 1 represents a side elevation, partly is a plan View of the same. Fig. 3 is a View of the left-hand side of the feed end of the machine. Figs. 4 'to 6 are views of details hereinafter referred to. Fig. 7 is a detail view of the journal of one of the rollers; and Fig. 8 is a detail of one of the rollers audits shaft,showing the pipe through which the heating or cooling medium is supplied.

The heating drum or cylinder 2 is mounted upon a strong hollow shaft '3,revolving in bearings 4, fixed in square holes in the heavy side frames 5. Radial holes or recesses 6 are made around the outer portions of the side frames, communicating with the slots or openings 8 through the sideframes. A hydraulicram barrel 9, a separate view of which is shown in Fig. 5, is placed in each hole 6, with the flange 1O bearing against the inner end of the hole. This is all that is required to retain the lower barrels in position; but the two upper ones on each side of the cylinder and each side of the machine are preferably bolted to the side frames as well. The end 12 of the ram 13.is reduced in diameter to fit the hole 14 in the under side or outside, as the case may be, of the bearing-block 15, one of which is fitted in each slot or opening 8. These bearing-blocks form bearings for the ends of the shafts 16 of a number of pressurerollers 20, disposed around the lower half of 'seriaino. 51,427. (No model.)

the cylinder 2. The hydraulic-ram barrels are supplied with water by pipes (not shown) connected to them and to the pressure-pipes in any convenient way. When the hydraulic pressure is turned on, the rollers 20 are pressed radially toward the cylinder 2. Springs 11, connected to eyes 11 and 12, maybe employed, if desired, to force the horizontal or approximately horizontal rams back into their barrels when the hydraulic pressure is removed.

The endless blanket 22, of greater width than the fabric to be treated, passes between the cylinder 2 and the rollers 20 and returns back underneath around the adjustable guide or tension roller 23.

Oomparatively light frames 25 are secured upon the top of the side frames 5 in radial slots 26, in which bearing-blocks 27 are fitted to form bearings for the heating-rollers 28, disposed around the upper part of the cylinder 2. The rollers 28 are pressed toward the cylinder 2 by the screws 29 on each side.

The ends of these screws abut against the blocks 27, and they are provided with adjustable screw collars or nuts which bear against the india-rubber blocks 30 in the recesses3l in the tops of the'slots 26. (See Fig. 4, which represents a portion of one of the frames 25in section.) The rollers 28 are hollow and are heated by steam or other means. Our object in using independent heatingrollers-that is to say, not using the pres sure-rollers for heating purposes-is to pre vent the pressure-rollers being unequally expanded, and thereby preventing them acting with uniformity.

cooling pressure-rollers of the cooling-cylin- Ider as regards the unequal contraction of the The same applies to the pressure-rollers, although not to the same degree.

The pressure-rollers 20 are driven by a wheel 43 at each end from the spur-wheels 40 and 41, mounted upon each end of the shaft 42, passing concentrically through the hollow shaft 3 and mounted in bearings in the standards 44. on the side of the machine. In

this way the rollers 20 are positively driven the machinethat is to say, half the rollers are driven by the wheel and the others by the wheel 41. The wheels 43 on the ends of the shaft 16 of the rollers 20 and the wheels 45v on the ends of the shafts 46 of the rollers 28 are of such a relative size to each other and to their rollers that both sets of rollers are. driven at the same peripheral speed. The cylinder 2 is mainly driven by frictional contact with the rollers 20 or, strictly speaking, by the traveling blanket 22, driven by such rollers. All the same the rollers 28 to some extent assist in driving the cylinder, although, no doubt, the wheels 45 might be dispensed with and the rollers 28 be driven by frictional contact with the cylinder 2.

The periphery of the cylinder is covered with paper or other suitable material, and when this covering is composed of annular sheets placed side by side, with the face of the sheets radially disposed, the inner edges of the sheets are made with radial projections 47 to fit longitudinal grooves 48 in the periphery of the cylinder 2. The frames 25 and the end flanges of the clamping-ring 49 are broken away in Fig. 1 to show this. The ring 49 is made with similar projections to the paper to engage the grooves, and the clamping-ring at the other end fits the shoulder 56 on the cylinder 2, as shown in the detail View Fig. 6, which represents a section of a portion of the cylinder with the two clamping-rings. The ring 55 is secured to the cylinder at intervals by the bolts 57, and the rings are drawn toward each other to compress the paper 58, Fig. 6, by the bolts 59.

On the same bed-plate 50 a duplicate arrangement to the above described is provided, excepting that the rollers 28 are cooling-rollers instead of heating-rollers and are cooled by circulating a cooling medium through them or in any other convenient way. The shafts 42 may be driven by bevel-wheels 52 on one end, driven by bevel-Wheels 53 on the countershaft 54, mounted and driven in any convenient way. The cooling arrangement is shown the same size as the heating arrangement, but in most cases it will be considerably smaller.

The fabric 80 to be treated passes from the roller or beam over the guide-roller 61 between the heated steam-chests 62, over the guide-roller 63 between the blanket. 22 and the cylinder 2, over the guide-roller 65 between the cooling-boxes 67, over the guideroller 68 between the second blanket and cylinder 2, over the guide-roller 69, and is wound onto the roller 70. The object of the steamchest is to heat the fabric without discharging the moisture from it, so as to get a superior finish when the pressure is applied.

The cooling boxes or chests 67 are cooled by circulating a cooling medium through them, and their function is to reduce the temperature of the fabric as it passes from the hot-pressing to the cold-pressing process.

The heating (or cooling) medium is supplied to the rolls in the manner shown in Fig.

8, in which 71 represents the supply-pipe leading to the hollow roll and provided with suitable gland 72 and backing 73.
